builder can i use DLMT for gabapentin? need help because dose is large/ml

the DLMT is adjustable with as many or as little HOLD's a s needed, so i slept on it, and i want to use it for another medication that i take, gabapentin 900mg

...but when i did the math the amount of ml is humongous, so i was wondering if there's a way to make it in less liquid?

my total daily dose is 900mg gabapentin divided into 3 equal doses (300mg) every 8 hours.

with the 1:2:8 ratio, that comes to

                                  900mg:    1800ml:    7200ml    for ONE DAY lol!  or

  (10 x 900mg pills) 9000mg:  18,000ml:  72,000ml  for 10 days lol!  (total of 90,000ml liquid suspension)

gabapentin suspension keeps for up to 90 days refrigerated and is almost 100% soluble in H2O, so i want to use H2O as my solvent and then use HUMCO suspension liquid (similar to ORA PLUS) as my "8" in the 1:2:8 ratio

but 9,000mg in 90,000ml is a ton of HUMCO suspension liquid to be drinking and buying/expensive! so i wondered if there's a way to adjust this so i can still use  the DLMT method for my gabapentin.

MANY THANKS IN ADVANCE for any help with this!
